Abstract: Bioelectronic sensors are provided employing a thin surfactant polymeric electrically conducting layer to which may be bound members of specific binding pairs. Binding of an analyte or a reagent to the specific binding pair member layer may change the electrical, optical, or structural properties of the layer for measurement of analyte. The change in the polymeric layer provides for a sensitive measurement.

Abstract: Methods for producing a room temperature stable, phase pure .alpha.-C.sub.3 P product, and compositions derived therefrom, are provided. In the subject method, a tricalcium phosphate source is heated to a temperature sufficient to convert substantially all of said tricalcium phosphate source to a substantially phase pure .alpha.-C.sub.3 P product. The temperature of the resultant product is rapidly cooled to a temperature below about 700.degree. C., resulting in a room temperature stable, reactive .alpha.-C.sub.3 P product. The resultant .alpha.-C.sub.3 P product may be milled to provide an .alpha.-C.sub.3 P composition which may find use in the preparation of calcium phosphate cements.

Abstract: Separation media for electrophoresis, and methods of filling and flushing of electrophoretic devices such as capillaries are described. By preparing submicron to above-micron sized cross-linked gel particles and using gel swelling equilibrium concepts, such devices can be easily filled and flushed. Gel particles can be prepared by inverse suspension, precipitation and suspension polymerization. These particles can be swollen and collapsed by small changes in temperature, pH, and ionic strength of solvent. Other approaches involve the formation of reversible cross-links by use of polyelectrolyte complexes, chelating agents or copolymers of hydrophobic and hydrophilic repeat units. Finally, reversibly solubilized systems may be used to change the viscosity of the media.

Abstract: Farnesyl derivatives, particularly farnesyl acetate, are used to reduce the level of protein farnesylation in a mammalian host. The activity of proteins which require farnesylation for function is thereby reduced. The compounds may be administered to patients to reduce the overall level of ras protein activity, either alone or in conjunction with other drugs which act as competitive inhibitors of farnesyl protein transferase.

Abstract: A method for detecting multiple subpopulations of analytes of interest in a sample employing a complementary binding moiety to each of said analytes bound to a solid support, wherein each analyte and its complementary binding moiety comprise first and second members of a specific binding pair (msbp) respectively is provided. The method includes the steps of forming a mixture of known proportions of multiple subpopulations of said complementary binding moieties, wherein each subpopulation comprises a different complementary binding moieties, contacting the sample with the mixture so that specific binding pairs are formed on the solid supports, and relating the presence of analytes of interest in the sample to the formation of specific binding pairs associated with each unique proportion of said multiple subpopulations. The method can be performed with solid supports of a single average size and a single fluorochrome and without the need for using three detection systems (fluorescence FS & SS).

The dyes find particular application in gel electrophoresis and for labels which may be bound to a variety of compositions in a variety of contexts.

Abstract: ERF-1 is shown to be a transcriptional regulator of the expression of the estrogen receptor, where elevated ERF-1 is related to elevated expression of the estrogen receptor. By monitoring the level of ERF-1, one can relate phenotypic characteristics of carcinomas expressing ERF-1 as prognostic of the response of the tumor to various therapies. In addition, ERF-1 may be used for screening therapeutic drugs which may act as antagonists to initiation of estrogen receptor transcription.

Abstract: Chemotactin, diethyl phthalate, is shown to be a chemoattractant secreted by H. pylori. Chemotactin attracts phagocytic cells with a resulting inflammatory episode. Chemotactin and its metabolites may be used for diagnosis and monitoring courses of infection by H. pylori or other chemotactin secreting organisms. In addition, chemotactin may be used in research for studying the inflammatory process, for identifying new drugs for modulating chemoattraction and activation of phagocytic cells, and for inducing an inflammatory response as a therapeutic intervention.

Abstract: Methods and compositions are provided for the determination of cross-reactive alleles, where there is no antibody which will specifically distinguish between the two alleles. Particularly, the method employs an antibody which binds to the two alleles bound to a surface, an antibody specific for one of the alleles, a labeled conjugate which binds to a consensus sequence present in both alleles and positive and negative controls. By having an enhanced value where the interfering allele is present as compared to a value for the target allele, one can distinguish between the various alternatives involving the presence or absence of one or both alleles.
